Alnus glutinosa, also known as black alder, is a species of tree in the family Betulaceae. It is native to Europe, and in moderate climates, it is a fast-growing tree, typically reaching around 20โ30 m in height. The tree thrives in wet locations where its association with the bacterium Frankia alni enables it to grow in poor quality soils. It plays a very important role in the ecosystem as it enriches the soil in nitrogen content, and the chemicals it releases into the soil inhibits the growth of competing species. Its wood is useful in carpentry for items including furniture, flooring, and paper pulp.
Growing Details
Black Alder is one of the easiest trees to grow. It needs moist soil and ample sunlight. The seeds need to be planted in spring. The tree is known to be invasive and should be managed properly, but it is also very beneficial for the ecosystem as it enriches the soil in nitrogen content.
